Consumer 3D printer used to create human tissue

Researchers from Carnegie Mellon University in the US, have adapted a low cost MakerBot 3D printer to print with biological materials. The team hope their work could result in a world where transplants are no more required to repair damaged organs.

Traditional 3D printers build tough objects layer by layer, typically from substances such metal or plastic. Because each layer demands sturdy support from the layers underneath printing with soft stuff has been highly challenging.
